Abstract
The invention discloses a manufacturing method of an asphalt-concrete speed bump, wherein asphalt concrete mixture comprises asphalt, aggregate, mineral powder and BA-3 anti-stripping agent; the aggregate is mineral particles, stones or gravels, the aggregate with the grain diameter of 0.1-2.36mm is 30-34wt%, the aggregate with the diameter of 4.75-9.5mm is 23-27wt%, the aggregate with the diameter of 9.5-19mm is 27-31wt%, the mineral powder is 5-7wt%, the asphalt is 4-6wt%, and the BA-3 anti-stripping agent is 2-4wt%, and the mass percentage sum of each component is 100%. The asphalt-concrete speed bump meets relevant technical quality requirements and is suitable for wide popularization, and a construction method is simple.
Description
Technical field
The invention belongs to the road construction project Material Field, be specifically related to a kind of making method of asphalt concrete deceleration strip.
Background technology
According to archaeological materials, Britain, France have adopted pitch to build bitumen macadam between 1832～1858 years, and Shanghai begins the asphalt road surface in the twenties in 20th century.Bituminous pavement has been widely used in urban road and arterial highway after 1949, becomes the maximum a kind of high class pavement of present Chinese making area.Pitch is bonded to integral body with the mineral pellet, gains in strength and strengthens the road surface and resist the ability that driving destroys, and the road surface is had a water resisting property.The bituminous material that is fit to the build road surface is mainly petroleum pitch, coal-tar pitch, and rock asphalt.Weather and the traffic conditions in highway section with bituminous pavement kind, area are different, and the character of pitch also can be different with label, breeze, the size of gathering materials, ratio, to make the bituminous pavement quality also different.Gathering materials is the common name of asphalt pavement material mineral pellet, and pitch has good clinging power, plays skeleton function and filling effect in ground surface material.Sometimes need that several are thick, fine granules mixes and forms needed grain size distribution.Breeze commonly used is limestone powder, and breeze also will have good clinging power with pitch, can resist the abtragung of water.
Summary of the invention
The object of the present invention is to provide a kind of making method of asphalt concrete deceleration strip, asphalt concrete deceleration strip of the present invention meets the correlation technique specification of quality, and constructional method is simple, can extensively promote.
For achieving the above object, the present invention adopts following technical scheme:
A kind of making method of asphalt concrete deceleration strip, asphalt concrete prescription of mixed materials be pitch, gather materials, breeze and BA-3 antistripping agent; Described gathering materials is mineral pellet, building stones or chad, and wherein particle diameter is the 30-34wt.% that gathers materials of 0.1-2.36mm, and particle diameter is the 23-27wt.% that gathers materials of 4.75-9.5mm, and particle diameter is the 27-31wt.% that gathers materials of 9.5-19mm, breeze 5-7 wt.%; Pitch 4-6 wt.%, BA-3 antistripping agent 2-4 wt.%, the mass percent sum of each component is 100%.By prescription each component of asphalt concrete compound is mixed, after artificial cooperative mechanical is heated with stirring to 155-165 ℃, put into thermos van.
Remarkable advantage of the present invention is: asphalt concrete deceleration strip of the present invention meets the correlation technique specification of quality, and constructional method is simple, can extensively promote.
